Classic signs of alternator failure..... Have charging system tested if you want further closure. Doubtful any other problems associated with this. Make sure battery has full charge

You need to take it back to the mechanic shop and insist they drive it on the highway or go somewhere else.

Check battery connections and have battery and charging system tested.

Stop using it & take it to a repair shop
If you got codes,why would you continue to use the car
for a week or more ,verse using the codes to diagnose the
problem?

If you have 25 miles to drive with that serious missfiring going on, I would first try to find a repair shop closer to you. It need not be a Volvo shop. Failing that, I would have it towed. Since the towing distance may be greater than 5 miles, investigate joining a road hazard protection program first (like AAA or others). Once signed up, then have it towed under the new protection. I think you will find it cost effective to do that rather than just calling a tow truck.

I would say that you need to replace the alternator. The car was running on the batteries power. When you drove the car, it ran the battery completely dead.

If the battery is strong and charged, starter is fine, car ran okay while getting progressively worse until it died and won't restart now, might be fuel filter or pump. I've dealt with two cars with fuel filter issues. Both would idle fine, but run progessively worse under load and eventually die and not start although everything else checked out. Engine turned fast enought to start, battery strong, alternator fine, air cleaner clean, all that. No start. Changed fuel filters and done. Everything back to normal. Both cars were about model year 1990 (1989 and 1991). Replaced one in a parking lot and car fired right back up and powered on home just fine, whereas the week leading up to it it ran worse and worse, hesitated on acceleration and finally would die if you hit the gas. Fuel filter may be in engine compartment. Looks like a canister with an in and an out for fuel. Pump is in gas tank and is way more work and money. Good luck, hope this helps.

check the main fuses, those big ones, if this won't help take a look at the Groud wire. Make sure The Engine and vehicle Body is Properly connected to Battery GND (-12V).

Please update me about your Progress

Good Luck

Internal gear selector in Tranny is shot...try replacing with used..or get to a tranny shop..Good luck

It could be a number of things but the main problem for that type of noise is the lifters or rocker gears
